When an electron is

injected in the ion cavity, it

is submitted not only to

the accelerating force, but

also to a restoring

transverse force, resulting

in its wiggling around the

propagation axis. Because

of this motion, the electron

radiates x-rays.

Laser driven betatron radiation

1. High peak spectral brightness

2. Ultrashort duration

3. Very small source size
